IMPROVEMENT IN FISHING LINE SINKERS.

TO ALL WHOM IT MAY CONOERN:

Be it known that I, JOHN R. MAR'TIN, of Boothbay, in the county of Lincoln, and State of Maine, have invented a new and improved Fish Sinker or Fishing Lead; and I do hereby declare that the following is a full and exact. description thereof, reference being 'had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a. perspcctiveview; and

Figure 2, a. side elevation and section.

A is a nut or burr, working upon two disconnected parts of the staple B, as shown in Figure 2. C is a lchamber or cavity in the body of the lead J J. D is a door, working'upon the hinge O, and fastened,-whcn closed, by the screw K. lE is a hawse, bar, or arm of copper, composition, or other metal, connecting with the body by a screw at M. F and G are weights of lead, or other heavy substance, made of proper size and form to fit the chamber O'. H H is a plate of copper, composition, or other metal. L and IWI are swivels, which may be dispensed with if preferred. The body, J J,-'of lead or other metallic substance, is run or moulded in any desired sizc or form upon the plate H. of copper, composition, or other metal, of properly corresponding size o and form, and firmly held thereto by the shoulders N N, by the staple B, of copper or other metal, (which is itself cast in the body and additionally secured by the screw 17,) by the screw of the arm E at M, which passes in through the plate into the body, and by small screws inserted ad lz'bz'tunz. The nut A is sneiently large to prevent the swivel L from falling down.' Y

The general shape or" the sinker here adopted by me is old, but the arrangements above named and described are all new, to the best of' my knowledge and belief. The advantages of this Sinkel' over all others will be apparent. It may be rendered of greater or less weight by means of the loose Weights fitting the chamber, and

so used for dierent depths of water. It may be readily'detached from the line, and the disentangling of fishermens lines will be thus greatly facilitated. The hawse is readily detached, and the sinker is then much more conveniently used for a. sounding-lead. v i

I claim as my invention- 1. The connection of a plate of copper, or other hard metallic substance, with a body of lead, or other soft metallic substance, and the arrangement of a chamber therein enclosing weights of lead or other heavy substance, either or all of which may be removed 0r replaced at pleasure.

2. The fixing firmly in the upper part of the body of a staple of copper, or other metallic substance, with disconnected parts, (a'ording suicient space for the admission of a swivel or line,) and a nut or burr working upon both parts of the staple -at the same time, or one part. alone, so that the sinker may-be detached from the line and replaced at pleasure.
